Abstract

"PROCESSO PARA ENRIQUECIMENTO DE MINéRIO NIQUELìFERO OXIDADO". Este processo para enriquecimento de minério oxidado de níquel compreende a transformação do minério em polpa, lavagem da polpa de minério por pelo menos 1 minuto, classificação do minério lavado num ambiente úmido de modo a separar pelo menos uma fração fina de uma fração granular, submetendo a fração fina a separação densimétrica em uma densidade divisora entre 1,7 e 2,5 e recuperando a fração leve separada como minério enriquecido."PROCESS FOR ENRICHING OXIDIZED NICKEL OXIDE ORE". This process for enrichment of oxidized nickel ore comprises the transformation of the ore into pulp, washing of the ore pulp for at least 1 minute, classification of the washed ore in a humid environment in order to separate at least a fine fraction from a granular fraction, subjecting the fine fraction the densimetric separation at a dividing density between 1.7 and 2.5 and recovering the light fraction separated as enriched ore.
